This invention pertains vto driers for noo- V dies and similar dough products.

One of the objects of this invention is to provide a device in which the product may be quickly and thoroughly dried in a simple and effective manner.

Another object is to provide means whereby the product may be given an extended travel while subjected to a draft of air.

Further objects will appear from the following description, taken in connection with theaccompanying drawings, in which-- Figure 1 is a' plan view of a drier embody- -ingthis invention;

Referring to the drawing, I designates'a supporting frame or base.- Mounted for oscillating movement upon the'base 1 is a series of trays 2 and 3. Each is constructed wlth an outer frame 40 provided with guide rails 41 adapted to receive an. inner frame 42 upon tom 22. The screen or bottom 22 is thus removably mounted in the outer trame'between the rails 41. In order to provide for removing the screen, the outer frame is provided with aremovable end board 43, seated in grooves in the side pieces and secured in place by a clamping bolt 44. Tim provldes for. renewal of the screens when worn. When in place, the screens are secured by screws 45. Inthis series alternate trays are rigidly connected together by straps 4 or other suitable means. The straps 4 connect the trays 2, while similar straps 5 connect the trays 3. Each group, of trays is supported for oscillatinno'n the base 1. ,Pivoted at 6 onsaid base are links '7, which are pivoted at their other endsb to mature trays of group This mounting permits an endwise oscillating movement for these trays. .In a similar manner, links 9,

# PiVoted'at 10 to one of the tray 0f group 2 and atll to the base 1, support the group 2 for similar oscillating movement,

The trays 3 are connnected attheend of the machine by a bracket 12. This bracket has pivoted thereto at 13 a pitman 14 connected with an eccentric15 on a shaft 16. One of the trays 2 has pivoted thereto at 17 a pair of pitmen 18, each of which connects with an eccentric 19 on the shaft 16. The eccentrics 15 and 19 are oppositely displaced on the shaft 16, so that, when said shaft is rotated, the pitmen 14 and 18 will impress upon the two groups. of trays opposite oscillations. n The shaft 16 carries a pulley 20 connected by a belt 21 to any suitable source of power, not shown.

The trays 2 and 3 are preferably constructed so that their bottoms 22 are arranged to slope in opposite directions in successive trays. For instance, in Fi re 2, the bottom of the upper tray slopes ownwardly to the right, while that of the second tray slopes downwardly to the left, and so on, alternately throughout the stack. At the left-hand end of the upper tray, a box or hopper 23 may be provided to receive the material as it is delivered to the drier. The discharge end of eachtray is provided with a gap 24 between the termination of its bottom 22 and the end of the which is stretched a screen or perforated bottray, so that the material, when it reaches that end of the tray, will'fall. through the gap to the next tray beneath. The last tray 2 may be provided with an extension 25 for discharging the material.

Enclosed in the lower part of the frame 1 is a housing 26 providing an air compartment communicating at its upper portion with the stack of trays. The sides of the trays are formed with rabbet joints, as indicated at 27, Figure 3, so as to permit relative movement thereof, while at the same time providing a substantially continuous side wall from bottom to top at each side of the stack of trays, thus providing together a vertical stack.

The housing 26 is provided at intervals therealong' with lateral openings in which are mounted fans 28 mounted on shafts 29. The shafts 29 are belted together by belts 30'so as to run together, and one of these shafts set up a draft of air through thecompartment 26 and upward through the stack of trays, the perforated bottoms permitting circulation of air upwardly therethrough. he material is fed into the On account of the slope'of the bottom, the oscillation of the tray will causethe material to move gradually toward the lower end thereof, after which it drops through the gap-24 to thenext tray vbeneath. This tray, having its "bottom sloped in the opposite direction,.the'

material will travel back therealong to be delivered in a similar manner to the succeeding tray.

charged eventually at the discharge end 25 of the last tray into any suitable receptacle,

not shownf Dur n g its travel, the materlal is subjected to a continuous draft of air set up by the fans 28, As it travels along the different trays, it gradually becomes drier until it is finally discharged in the completely dry condition. It Wlll be noted that the incoming air, which is dry, impinges first upon that part of the material from which most of the moisture has been removed. As the air passes upwardly through the trays, it gathers moisture.

, Accordingly, the drier air is run into contact.

with the'drier material. This arrangement promotes the rapid and complete drying of the material. r While this invention was designed particularly for drying noodles, it may be used for drying other dough products.

While the apparatus has been described as .a unitary machine, it will be understood, of course, that certain combinations may be useful without other parts of the complete combination, and the use of such subcombinations is contemplated by the invention. It is further obvious that various changes may be made, within the, scope of the appended claims, in the details of construction without departing from the spirit of this invention; it is to be understood, therefore, that this invention is not limited to the specific details shown and described.

Having thus described the invention, what is claimed is:

1. A drier for noodles and the like, comprising, a vertical stack of trays having perforated bottoms, the outside walls of said trays joining at their meeting edges so as to form be outside walls of a vertlcal shaft, means v device at the hopper 23, where it 15 is deposited upon the bottom of the first tray.

r In this manner, the material will travel; successively through all the trays tobe disfor shakingsaid trays, and means for passing air through said shaft.

2. A drier for noodles and the like, comprising, an enclosed frame having an air chamber therein, a vertical stack of tra 5 each having a perforated bottom and upri t outside walls, the walls of said trays joining at their meeting edges so as to fdrm the outside walls ofa vertical-shaft, means for blowing air into said chamber to pass? upwardly at their meeting edgesso as to form theoutside walls of a vertical-shaft, means for connecting alternate trays together toform groups,m'eans'for blowing air into said chamher to pass upwardly through said shaft,and
